17、goats, a study from the University of Roehampton and the University of Sydney has found. The research which involved kangaroos, marsupials(有袋类动物)that were never domesticated, at three locations across Australia, revealed that kangaroos stared at a human when trying to access food which had been put
18、in a closed box. The kangaroos used eye-contact to communicate with the human instead of attempting to open the box themselves, a behaviour that is usually expected for domesticated animals.Ten out of 11 kangaroos tested actively looked at the person who had put the food in a box to get it. Nine of
19、the 11 kangaroos additionally showed eye-contact between the box and the person present, a strong form of communication where they looked between the box and human.The research builds on previous work in the field which has looked at the communication of domesticated animals, such as dogs and goats,
20、 and whether intentional communication in animals is a result of domestication. Lead author Dr. Alan McElligott previously led a study which found goats can understand human signals, including pointing, to gather information about their environment. Like dogs and goats, kangaroos are social animals

22、 is not related to domestication. Indeed, kangaroos showed a very similar pattern of behaviour we have seen in dogs, horses and even goats when put to the same test. We hope that this research draws attention to the cognitive(认知的)abilities of kangaroos and helps promote more positive attitudes towar

The self-heating
